NEW YORK (KWWL) -- If you want to lose weight, you might want to lose the plastic.

A recent study published in the Journal of Consumer Research shows consumers that pay for groceries with cards spend more than those who buy with cash and people who use plastic to pay bought more junk and impulse foods than cash carriers.

In fact, studies that show a relation between cards and spending go back to 1979.
